The increased number of slave holding states would upset the delicate balance of power that existed in the US legislature where the lower house was in the hands of the more populated northern states and equality ruled in the Senate. Slave Power was something that the Whigs considered a threat to both Freedom and to Democracy.
Manifest Destiny is the Western Expansion movement in American History. in and of itself hit has nothing to do with Slavery. Texas was a slave-holding state, and in fact, was part of the Confederacy. No states admitted to the Union after l850 ( this was the so-called Missouri Compromise associated with Lincoln) were permitted to have slave-holding proper. again, they are two different concepts. a Tangential point is that some Indian tribes had black slaves!
As a result of this theory that white settlers were 'destined' to colonize the whole of what today is the USA, new territories were settled and these territories were coming up for the status of US States. The discussion about slavery had already been going on for some time between the slave-holding South and the Northern States. In the until then existing States the South had an equality if not a majority position in the discussion, and the issue had for the time being been more or less settled in the Missouri Compromise.
The new States however threatened to upset the balance of power between the slave-holding States and the rest, and the Southern States therefore insisted that newly established States should also formally become slave-holding States. The Northern States opposed this, as did a sometimes large part of the inhabitants of the newly colonized areas.

Since "Manifest Destiny" was the belief that the U.S. was ordained by God to spread to the Pacific Ocean, the annexation of Mexican territory is the best answer here. The other issues deal with slavery or slavery in the territories of the United States.
whether slavery would spread across the United States
Manifest Destiny was the belief held by Americans that the U.S. should own all of the land on North America from the Atlantic to the Pacific. This was achieved when the U.S. won the Mexican-American War and acquired what is now the Southwestern U.S. However, acquisition of this land brought back up the slavery question, i.e. should this new territory be slave or free--an argument that would eventually lead to the U.S. Civil War. The manifest destiny also led back to popular soveignty!!!

Manifest destiny and slavery on acquired territories (specially Texas) motivated such conquest. See related questions.
whether slavery would spread across the United States
One policy of Jacksonian democracy was to avoid divisive debates over slavery. Another policy was the support of Manifest Destiny and westward expansion.
Manifest destiny started the dispute over the spread of slavery. Since before the Mexican-American War the states had argued about annexing new territory because of the spread of slavery. Also, this is more of a underlying factor and a personal opinion, I think that the northern population wanted to preserve the union so badly because the media had been perching manifest destiny for so long people didn't realize how bloodily and costly expansion could be. Many Americans were wrapped up in the success the US had had expanding to the west so they didn't really understand the true costs of war.
