be candy crowley, and cnn's john king, he's the host of "john king, usa," which comes up right at the top of the hour. and, john, first to you, are these contests on tuesday going to be the result -- the outcomes of these contests going to be the result of angry voters out there or the individual candidates and their specific differences? >> it's a combination of the two. but i think it is a test of the power of anti-incumbent sentiment out there in the sense that you have arlen specter in pennsylvania, a republican turned democrat, now once again, six years ago, you know, wolf, he had a primary from the right and president bush had to bail him out. now he has a primary from the left and president obama is trying to bail him out. it's a fascinating race up there, and it's a test whether seniority and stature matters. same thing in arkansas, blanche lincoln is the chairman of the agriculture committee, you need me, i bring home the bacon and influence. is that the right message when voters are saying the more power you have in washington, the less we like you. so, they're all big tests.
