Over on CNN, our friend David Frum writes:

The Republican fratricide in the November 3 special election in upstate New York may prove just an opening round of an even more spectacular bloodbath in Florida in 2010.

If by “bloodbath” he means, hard-fought primary, then yes, there will be one of those. You’ll probably see them in the Texas governor’s race, the California Senate and governor’s races, maybe New Hampshire and Connecticut Senate races, and maybe a House race or two.

But they happen, and while they can often use up resources, they don’t generally spell disaster for the general election. Democrats had a really hard-fought 2008 presidential primary, and things turned out okay on their end last year.

Barring some big surprise, the Democratic senatorial nominee in Florida will be Kendrick Meek. Barring a race-changing revelation or scandal, either Crist or Rubio will beat Meek pretty handily.

Frum’s larger point is that Rubio is hitting Crist for supporting Obama’s stimulus, without offering good alternatives: “Here’s the most important unasked question raised by the enthusiasm for Rubio among Washington conservatives: What alternative policy should have been adopted back in the spring, when interest rates had been cut to almost zero and the economy was still collapsing? Are vague bromides about big government anything like an adequate response to the worst economic crisis experienced by any American under age 80?”

I liked a one-year suspension of the payroll tax, but that’s just me…
