Very curious:

Stockman has missed 17 straight House votes since Jan. 9— including one on the $1.1 trillion omnibus federal spending package he promised on Twitter to vote against. That's unusual since, even though Stockman has a reputation as a Capitol Hill renegade, he missed only about a dozen major votes all last year.[..]After first dropping out of sight, the congressman recently was spotted on a visit to Egypt as a member of the House Foreign Affairs Committee — but where he's gone since then is unclear.

Stockman's staff won't say where he is. They have ignored more than six weeks of emails, telephone messages and social media posts from The Associated Press and other news outlets.

Cornyn, seeking his third term, has a campaign that's been more responsive: "It's up to Texans to decide if they think someone who doesn't show up to work or adhere to election law deserves a promotion," said spokesman Drew Brandewie.

Though skipping votes isn't uncommon for congressmen who are campaigning, Stockman hasn't done much campaigning, even with Texas' March 4 Republican primary now looming.

Stockman's House office staff has continued his Twitter stream in his absence, though it is missing some of his more colorful tweets. Remember, too, that Stockman's Senate campaign office in Texas was recently condemned and looked like it had been inhabited by squatters instead of campaign workers.

Not sure this is the best way to launch a serious campaign for the Senate, but then again, who really takes Stockman seriously?
