Two polls released Monday indicate Republicans might not have received the spike they were looking for following the nomination of Mitt Romney at the Republican National Convention last week.

According to a Gallup national poll released Monday, 40 percent said the convention made them more likely to vote for Romney, but nearly the same percentage, 38, said the convention made them less likely to vote for the Republican nominee.

The response was similar among independent voters nationally, with 36 percent saying they were more likely to back Romney, with 33 percent less likely.

Gallup has been asking that question since 1984, and the net impact from the 2012 convention is the worst on record for either party.

Romney’s acceptance speech received a tepid response as well.

Thirty-eight percent said it was excellent or good, while 16 percent rated it "poor" or "terrible." Gallup has been tracking this metric since 1996, and this was again the worst rating for a candidate from either party. The previous low was by Sen.

Some daily tracking polls conducted during the convention showed a significant bump for Romney, as he pulled into a 46-46 tie with President Obama nationally, according to the RealClearPolitics average of polls.

However, a survey from liberal-leaning Public Policy Polling (PPP) released late Sunday shows the convention, which took place in Tampa, failed to move the needle in that critical battleground state of Florida.

In a poll conducted entirely after the conclusion of the event, President Obama maintains the same 48-47 lead over Romney in Florida that he held last month.

Voters in the PPP poll are similarly divided as those in the Gallup poll over their impression of the convention, with 33 percent saying it made them more likely to vote Republican and 33 percent saying less likely.

Obama’s small lead over Romney in Florida is buoyed by independents in the state, who favor the president 51-39 over Romney.

The Gallup poll of 1,045 adults was conducted between Aug. 31 and Sept. 1 and has a 4 percent margin of error.

The PPP survey of 1,548 likely voters was conducted between Aug. 31 and Sept. 2 and has a 2.5 percent margin of error.
