Marco Rubio in CBS "Face the Nation" interviews during 2015

On Foreign Policy: Do not leave it to Russia to get rid of ISIS

RUBIO: Well, the problem with it is, number one, the Russians aren't necessarily targeting ISIS right now. They're targeting non-ISIS rebels, and it's part of an effort to wipe out any non-ISIS fighters on the ground, so they can turn to the world and say that the only choices are either Assad or ISIS. The second point is that the growth of ISIS will continue in Iraq. They are spread now into Libya, where they have become a very significant presence, increasingly in Afghanistan as well. Putin's interests at the end of the day are largely to prop up Assad, who has provided for them a foothold into the region. And so they are stepping into vacuum we have left behind. In an ideal world, you would be able to work with Russia to defeat radical jihadists.

On War & Peace: Boots on ground in Syria; coordinate with Kurds

RUBIO: Well, it's an important start. I think the broader issue is, what is the strategy? And I think the strategy has to involve more coordination with the Kurds and also with Sunnis, because you're not going to defeat ISIS, a radical Sunni movement, without a robust anti-ISIS Sunni coalition. So, I do think it's important tactical step forward. It needs to be backed up with increased airstrikes and so forth.

On Principles & Values: FactCheck: Senate attendance comparable to other candidates

• Rubio has missed 34% of his votes in the Senate this year.
• Bob Graham (D-FL) missed 32% of votes in 2003. That rate spiked to more than 70% as the race heated up.
• John Kerry's (D-MA) absentee rate was even higher--64% in 2003, and close to 90% after he had secured the nomination.
• Then-Sen. Obama (D-IL) missed 26% of his votes in 2007 and 64% in 2008, and skipped almost all votes directly leading up to the election.
