President Reagan demonstrated this over and over again in making progress toward his overall policy goals. President Clinton learned this and was able to reach many of his overall policy goals, particularly during his second term. In contrast, approaches where the President chooses a sort of insulation from the Legislative Branch or embraces a passive view that leaves the policy initiative largely or solely to Congress can only lead to an ineffectual Presidency.
Let's see, GOP's last few candidates... Romney, McCain, Dole, and Bush. 3 out of 4 lost. Bush had two close elections. All four are moderates, no where near conservative. Last conservative, Reagan. Won in two tremendous landslides. In two elections, he won something like 97 out of 100 states.
Yeah, why nominate a conservative like Cruz? We're doing so well with the moderates!

I would be paying attention to the polls above more so than any straw poll. Cruz is running an average of 6 points.
Early voting in Georgia. On the 20th of October this old Goldwater conservative voted against both Donald Trump and Hillary Clinton by casting my vote for Gary Johnson. Neither Trump or Clinton belong within a million miles of the Oval Office.
Those all important middle of the road voters need to hear what the candidate is for - specifically - and what his plans are. Being against Obama is not a plan. Being against Obamacare is not a plan. I think until well thought out plans that have the possibility of passing (means working together) are put out there - the Dems will remain in office.
But of course, nothing will actually change in American politics until Big Business/Unions etc are out of the back pocket of politicians.
