Is exterminator-turned-Rep. Tom DeLay the most powerful man on Capitol Hill? 

DeLay also won't surrender his impeachment obsession. As a clever political strategist, he surely knows that impeachment would be a disastrous, chaotic mess that could only discredit Republicans. But as an ideologue, DeLay can't control himself. In fact, he seems to be the person who pushed the Judiciary Committee to expand its investigation into campaign finance. The irony of DeLay's activism is that his intransigence may prevent any punishment of Clinton. If impeachment fails in the House, DeLay's stony opposition may defeat censure as well, allowing the president to escape scot-free.
