We're still in Iraq, and ramping up in Afghanistan, and while people will try to rewrite history Afghanistan was included in many of the later war protests. Happened to see war protests every week being followed on MSNBC or CNN since Obama took office? Seen any random protesters camping out outside of the White House or Chicago when Obama goes home? Remember the legions of Democrats complaining about spending and the deficits for 8 years and now are completely silent? Rememeber MoveOn.org labeling General Petraeus and General Betrayus while under Bush while remaining relatively silent about him when Obama's shifting him into command of Afghanistan? Remember great outrage at the notion of using the "nuclear option" by democrats and then turning around and defending the congresses hope to potentially pass something with "a simple up and down vote"?
Or you know, you could step out of your political grand standing and view this realistically. Human nature suggests that individuals complain in a different fashion depending on the circumstances, specifically if its "their" guy or not and the benefit it'll get them.
For the "their guy" mentality, look at sports. TO was on the 49'ers and generally viewed as a malcontent that is a jackass, but once the Eagles got him Eagles fans thought he was great and ignored it until he was gone. Then the cowboys got him and suddenly forgot about their hatred for him when he was on a division rival and spiked the ball on the Star and embraced him, till he was gone and then it was back to bashing. Hell, for my team, watching Washington Redskins fans suddenly talk about Donovan McNabb as a top 5 quarterback when all the way up to last year they would've argud he's overrated is a perfect example. Human nature is to be more defensive and forgiving for "your guys".
Additionally, you tend to be more likely to keep complaints or issues "internal" rather than external. How many businesses, groups, or sports teams do you hear referencing that? Keep it "in house". If you have a problem with "your people" then you want to fix it to improve YOUR people. Highlighting said problem publicly would then be counter productive to that goal, as while it may fix the problem it creates a new one as people see disfunction, get the problem further pointed out to them, and allow them to exploit it.
Which leads to the self interest and end goal issue. If you're upset with "your guys" but still think they're BETTER than the other guy, you try to fix the issue in such a way that will hopefully fix it while not helping the other guy win. Why? Because then you're cutting off your nose to spite your face, potentially making things WORSE rather than fixing anything.
In politics this is why throughout history when people are upset with THEIR party or ideology the fervor is usually much quieter, much more restrained, much more spoken about in calm and more neutral tones publicly. This is because actions like loud protests, heated rhetoric, continual harping, and other such actions inspire the potential for change in a candidate by hopefully hurting the amount of funding and support they get by swaying public opinion. The problem with doing this against ones own party is that by hurting funding and support you hurt your chance of having your guys elected, and if you think your guys (Even with their problems) are BETTER than the other guys then you're cutting off your nose to spite your face. This is why both parties tend to go for a more subdued approach against their own side most times.
And even then, at times it does ramp up though typically relative to the rest of the reaction to a party. For example go back and look at 2006 and much that was coming out of many conservatives at that time. Donations were crappy, turnout wasn't that great, many conservatives were stating they were staging protest non-votes due to Republicans failing to adhere to their beliefs, etc.
Is that as loud as its now? Absolutely not. But wishing for that to occur is just unrealistic and is expecting conservatives to be held to a standard that not a single political group has done in modern times. To reserve your condemnation solely for them is hollow.
