Move to the center
In an unsurprising move to the Right, Senator Clinton is a co-sponsor of a bill to increase the size of the Army by 80,000. Dems aim to increase army size.
This is another move for her to appear Hawkish. She wants that uncommitted center vote and as much of the Right as she can fool. Don't believe it. She won't vote for it when the time comes. She will complain that some amendment has 'poisoned' the bill.
Besides, the bill is largesse anyways. The Congress already voted for a 30,000 troop increase and the Army is having difficulty in meeting that goal. Remember when all the news was "Army can't meet it's recruiting goals?" That was because of the base increase of the Army, not because there aren't willing recruits signing up.
Anyway, don't be fooled by Hillary's machinations.
