I do not think you can reasonably describe the entire contest between the armies of the Potomac and Northern Virginia in 1864 and 1865 as a "siege". That word does describe what happens once Lee is forced into permanent defense around Petersburg, but it hardly captures the war of attack - counter-attack that went on before then or the sad ending that comes once the siege of Petersburg is over.
McClellan's greatest problem was that he had no sense of politics; you see that in his constant refusal to understand the difference between the personal acclaim that comes with publicity and the power that comes to a military leader from being someone whom the politicians can trust. McClellan expected somehow to be able to dominate the politicians, even though they were in charge; like Napoleon he did not consider it necessary to form any alliances of sustained interest. In a country like France in the 1790s, where democracy was itself an experiment, it was possible for a successful, popular general to ignore political representatives; for a country fighting a civil war with both sides acting through elected civil authorities, that was folly of vanity.
The operations before Petersburg weren't really a siege. One can argue that Lee's 50,000 troops neutralised Grant's 100,000 (all that was left of ca. 250,000 troops because of how reduced that force became after the bloodletting of the Overland Campaign and the detachment to the Valley)
Lee in July 1862 was as pinned to Richmond as he was to Petersburg in July 1864. In fact, McClellan pinned more troops than Grant, by a large margin. You should note that Grant abstained from making any serious effort against Petersburg or Richmond for almost a year. He spent much time asking for more troops (i.e. 6th and 19th Corps), because he couldn't cut the railroads without them, and noted that he didn't have sufficient troops to make an offensive, but he had more than needed for a strict defensive. In mid-July his suggestion of withdrawing so he could send off troops to Sherman, because he'd given up on the idea of capturing Richmond, were not well received.
When Grant got the troops he'd spent H2 of 1864 asking for, he launched a successful offensive a mere 4 months after their arrival, although of course this was the winter, and Grant sensibly didn't try and move troops whilst the roads were bad, much like McClellan in 1861-2.
