For example no mention is made of the Democrat opponent in 1864, General George McClellan. This role could easily be played by today's anti-war general Wesely Clark. There are other comparisons likely to be made, between the other lessor known Democrats of that era and those that occupy the stage today.
Without these details and with no direct comparison between Lincoln and Bush, the article fails (imo) to convey the historical linkage back to 1864.
