President Barack Obama visited Colorado University, sixth trip to a campus in a week, tried to gather as much support as he could from the young voters.

Obama spoke at the Boulder campus of University of Colorado, with as many as 13,000 sets of hopeful young eyes set on him. The optimistic and combative tone of the speech received huge shouts of approval among those assembled at the university to hear him speak.

The Democrat President did not spare any chance of attacking his opponent, former Massachusetts Governor Mitt Romney, saying that the Republicans are not offering anything more than the old disgraced policies they tried to sell the Americans before, Bloomberg reports.

"They have tried to sell us this tired, trickle down, you're on your own, snake oil before," Obama told at the gathering. "Those ideas don't work, they didn't work then, they won't work now, they did not create jobs, they did not cut the deficit."

The President, on his way to the Democrat convention which is due on Sept.4 in Charlotte, North Carolina, is visiting the key battleground states of Ohio, Virginia, Colorado and Iowa all of which he won in 2008. But, this time, it will be a close battle for him against Romney. Hence, Obama is on a mission of inspiring the young people, whose votes can pivot the needle of victory to his side.

"And what they're counting on is that you get so discouraged by this that at a certain point you say, 'You know what, I'm going to leave it up to someone else.' ... I'm counting on something different. I'm counting on you," said Obama attacking the opponents' tactics of painting a gloomy picture of his reign there by discouraging the voters to cast their vote.

In his effort to mobilize and register new voters, Obama had campaign volunteers distributing registration forms.

He even touched the much debated topic in education circles-making college affordable. He bashed Romney's plans for college affordability as being amounted to 'just borrow more money from your parents.'

"You made the investment in yourself," Obama told students. "And I want to make sure America is standing by you every step of the way."

The students at the rally seemed enthralled by Obama's talk and many expressed the desire to register, which was a positive sign. Other new registered voters said they can't wait to vote at the up-coming elections.
