The more important thing to remember about voting Republican this year is that a vote that gets a Dem in one state will hurt the pubbie in another state or the rest of the pubbies. This year, it IS all about protecting good conservatives and conservative seats, like Talent, Allen, Santorum, and Pawlenty, (to name just a few), and not about a tantrum over supposed RINO's. If we "lose" Tennessee, RI, Maryland, OH, and either house of Congress, then we lose power across the nation, making conservative voices LESS likely to be heard next time around.
If not supporting liberals just because they're "republicans" causes conservatives to lose power, maybe we deserve to lose...
