Story highlights The support for tougher gun laws rose to 55% in the newest CNN/ORC poll

Versions of those proposals are being taken up in the Senate Monday evening

Washington (CNN) Support for tighter gun control laws increased 9 percentage points after the Orlando terror attack, and support for background checks and other measures being debated in the Senate hovered around 90%, according to CNN/ORC poll released Monday.

The support for tougher gun laws rose to 55% in the newest poll -- the highest number since just one month after the shootings in Newtown, Connecticut, in January 2013.

But support for specific gun control measures was very strong, with 92% saying they wanted expanded background checks, 87% supporting a ban for felons or people with mental health problems and 85% saying they would ban people on federal watchlists from buying guns. Among Republicans, that number is even higher -- 90% say they favor preventing people on the terror watch list or "no fly" list from buying a gun. That number is at 85% for Democrats.

Versions of those proposals are being taken up in the Senate Monday evening -- but are all expected to fail along mostly party-line votes.

However, stricter gun control measures, like banning assault rifles and high-capacity ammunition clips, only won the support of 54% of respondents.
