This should be required, not unusual. It has worked well for other Republicans, notably Jim Talent in Missouri. At the very LEAST, folks get a positive introduction to the Republican, which makes it more difficult for the Rats to scare people into voting with a "he's going to enslave your children" message.
Shreveport demographer Elliott Stonecipher says Jindal needs 15 percent of the black vote, coupled with 2 out of 3 white voters, to win.
That would be a Big win. Blanco needs 35% white and 90% black. Roughly.
