From Eric Dondero:

Yet another Democrat in Louisiana has switched to Republican.

From TheRepublic.com:

Sen. Jody Amedee, of Gonzales, switched to the GOP on Thursday, in a move announced by the Legislature's Republican delegation.

Amedee, a trial lawyer in his second term, joins a growing list of Democratic lawmakers jumping to Republican ranks in advance of this fall's election. He's the third Democrat in the Senate to switch parties in the last five months, according to the Republican delegation.

This now gives the GOP a 21 to 18 majority in the Senate. Last year, the Democrats controlled the upper chamber by a similar majority.
