republican senators to target

for a third campaign (teddy bear and mail outs being the other two), we thought we'd target a few republican senators and try to get them to co-sponsor the bill. we're hoping for a list of 15 (we've got 12) so that we can get half a dozen new co-sponsors (hopefully). here it is:

brownback
coleman
collins
grassley
hatch
graham
martinez
snowe
warner
bennett
gregg
cornyn

we're trying to only put the ones that are supporters on the list since they're the most likely to co-sponsor it faster. dreamact1982, you know the most about the senators positions so we could use your help with which senators to add. once we have the complete list, we can post this on the facebook group and ask them to call specifically asking these senators to co-sponsor the bill

thanks
