Most freshman members of Congress do, in fact, wait for leadership signals on their statements and votes. However, none seems to be more blatant about it than Nevada's Rep. Dean Heller (R-NV2). Speaking of his position on the emergency supplemental funding bill (HR 1591) he tells the Las Vegas Review Journal: "Rep. Dean Heller, R-Nev., said his only "show stopper" in any compromise bill are troop withdrawal timelines that he said he strongly opposes. "My goal at this point is just to wait to see what leadership on both sides brings back," Heller said. "I don't want to set specific benchmarks and tie myself to those."
We are informed he is opposed to timelines -- that's been clear, but now he's "waiting to see what the leadership on both sides brings back..."
The implication is reasonably clear: Rep. Heller will do the bidding of the Congressional Republican leadership.
