1) the individual's track record-do they have a history of voting for the issues I find most important
2) generally the issues most important to me are taxes, gun rights, and whether they oppose income redistribution. I have found that the politicians who tend to trust people to own guns tend to believe that individuals are in the best position to decide what to do with their own money
3) other considerations. for example, if congress is a close call, I might support a GOP congressman who would get us a GOP SOTH even if the dem might be slightly better on the issues.
In Ohio, I plan on voting for Governor STrickland, though he is a dem. Why? as a freshman congressman he voted against the clinton gun bans despite strong pressure to sell out his constituents who tended to be poor miners and farmers who are dems but pro gun. His opponent-Kave IN Kasich changed his vote to favor the clinton gun ban (thus being the deciding vote) so as to ingratiate himself to the White House so WJC would sign Kasich's Penney-Kasich bill. He's a dishonest weasel and while he would be better overall in terms of his agenda, I will never vote for him after his sell out in 1994
I also will vote for Dem Richard cordray for AG of Ohio. Cordray is the most qualified individual in Ohio state government. A five time jeopardy champion, he is well respected as a professional. He also has an NRA A rating and spends most of his time prosecuting real criminals. His opponent-Mike DeWhine was one of the worst RINOs in the senate who was the only Republican to vote against the Bill that prevents slimey plaintiff's attorneys from suing gun makers over a crime committed with a gun that passed through at least two other hands after the maker sold it. DeWhine also threatened the Bush white house back when Jeffords swung to the left giving the dems control to do the same thing unless Bush appointed Dewhine's rinos to the bench and other offices.
On the rest of the races I will vote GOP. Rob Portman is a friend of mine and the most qualified guy running in Ohio in federal elections. His opponent is your classic gun hating bureaucracy loving welfare socialist. While I cannot vote for Steve Chabot, I support him strongly since he was another guy who always voted consistently for less taxes. The guy who upset him in 08 due to hordes of first time voting Obama bots, promised to be a fiscal conservative but became Nancy Pelosi's little but boy.
