Rand Paul tops Ron Paul in Kentucky, by a lot

With 99 percent of the vote counted in the Kentucky GOP primary for U.S. Senate ...

-Rand Paul outpaced Trey Grayson in every major region of the state, scoring his biggest win in the North, an area that includes the fast growing areas around Cincinnati and Louisville that have become reliably GOP. In that region, Paul won 65 percent of the vote, to Grayson's 32 percent.

-Paul won 109 counties; Grayson 11.

-Tear-away coattails: Grayson's regional vote this year is very loosely correlated (-0.002) with McConnell's in his win two years ago.

-With a third of registered Republicans casting ballots, more voted this time around than in the 2008 presidential primary (the GOP contest was wrapped up by that point two years ago) and the 2007 gubernatorial primary. At about 350,000 voters, it's the highest GOP primary turnout in available data back to 1990.

-The two main contenders in the Democratic primary for U.S. Senate each got more votes than Paul did in the GOP race. Fun fact, but ... registered Democrats in the state outnumber Republicans by nearly 600,000.

-Paul's totals trounced those of his father in the 2008 primary. In that election, the Rep. Ron Paul received 13,427 votes statewide. (At current count, the son as 205,221.)
