In the latest polls...

...from RealClearPolitics, five of the six most competitive U. S. Senate races -- Alaska, Arkansas, Colorado, Louisiana, New Hampshire and North Carolina -- are leaning Democratic. (Only Mary Landrieu, in Louisiana, is trailing her Republican opponent, Bill Cassidy.)

If a wily veteran like Landrieu can pull it out (as I'm convinced she will) and you throw in Iowa and Michigan, how in the heck are the Republicans going to take control of the Senate this year? I just don't see it happening.
