(CNN) - Comprehensive immigration reform has so far eluded President Barack Obama. But with his re-election victory in battleground states propelled by strong Latino support, Democrats and Republicans in Congress have a stronger interest in cultivating support from a group with growing political clout.

Here are five reasons why the time may be right for immigration reform to take hold in Washington.

1) The voters have spoken

Immigration reform may not have been the biggest issue in the election - the economy was paramount - but it is very important to a key segment of voters. Latino voters turned out in force and helped to tip battleground states in Obama's favor. The number of registered Latinos has increased by 26% in the past four years to 12.2 million, or 8.7% of all voters. That means this demographic will only increase its political power. Issues important to this minority logically will become increasingly important to both major political parties.

2) Obama promised but failed to deliver on immigration reform

Obama promised to push for immigration reform before the 2008 election and had to answer tough questions from Latinos about why that did not occur. At a forum by the Spanish-language Univision network, Obama was pressed to admit that he had fallen short and took responsibility for a lack of action. But the president also said he didn't promise he would accomplish everything he wanted right away.
