I’ve long wondered something about Washington, D.C.’s political dynamic.

How is it that some newly minted senators and House members always manage to make headlines immediately upon their arrival, while others languish in the shadows, hardly ever seen or heard?

Two brand new U.S. senators come to mind:  Republican Ted Cruz of Texas and Democrat Chris Murphy of Connecticut.

Both of these guys are pretty smart young men. However, Cruz has emerged as something of a loudmouth, such as when he accused decorated Vietnam War veterans John Kerry and Chuck Hagel of lacking sufficient regard for the military. Murphy keeps showing up on TV talk shows, saying just recently that President Obama paid too little in taxes in 2012 while campaigning for re-election saying that Republican nominee Mitt Romney, um, paid too little in taxes.

The Senate comprises 100 individuals, all of whom more than likely possess outsized egos. I am acquainted only with one of them: John Cornyn, Republican of Texas. Thus, I don’t know how many of them resent these new guys’ bursting onto the national stage while spending so little time earning their stripes.

Murphy, incidentally, represented Newtown, Conn., in the U.S. House of Representatives before being elected to the Senate this past November. Therefore, he brings instant cache to the debate over gun control, given what happened in December at Sandy Hook Elementary School. But he seems to be blabbing publicly about all kinds of things, such as Barack Obama’s tax returns.

Meanwhile, other members of both congressional chambers who have just as much to say as the new fellows remain silent.

Isn’t there enough room on the stage for more of these folks?
