It's been a big week for politics already, and now we get news that Gov. Mitt Romney is dropping out of the race for the Republican nomination for president ("suspending" is the term he used, as did Sen. John Edwards last week, but the effect is the same). Now, it's a two-person race on the Republican side, with Gov. Mike Huckabee winning over many evangelicals, and Sen. John McCain doing well with moderates and independents but working hard to win over party conservatives. Where does this leave the remaining candidates? How does this affect Republican voters? Why did he drop out now? And what does it mean for the Democrats? If you're a Republican voter, let us know what you think.
