Standing games at the SOTU

The Hill's Alexander Bolton was watching Barack Obama and Hillary Clinton closely during last night's State of the Union address. Here's what he discovered:

When Bush proclaimed, "Ladies and gentlemen, some may deny the surge is working, but among terrorists there is no doubt," Clinton sprang to her feet in applause but Obama remained firmly seated. The president's line divided most of the Democratic audience, with nearly half standing to applaud and the other half sitting in stony silence.

In one instance Clinton appeared to gauge Obama's response before showing her own.

When Bush warned the Iranian government that "America will confront those who threaten our troops, we will stand by our allies, and we will defend our vital interests in the Persian Gulf" Obama jumped up to applaud. Clinton leaned across Sen. Joseph Biden (D-Del.), seated to her left, to look in Obama's direction before slowly standing.

I'm not sure how much we can use such moments to predict how either candidate might behave in the Oval Office. But it is revealing to see how Hillary and Barack are trying to position themselves.
