[OSR stands with Israel]

1894- Gives Republicans Majority in Congress for a generation
1930-  Beginning of New Deal Coalition
1958- Guarantees democrats dominance of congress for the next generation
1994- Gives Republicans advantage in congressional elections

Not exactly Realignments but close

1918- Gave Republicans Supermajorites
1948- Validated new Deal Coalition
1980 - Cracked democrats advantage in congress

2008

[Senate Minority Leader Lord Voldemort]

1896
1932
1968
2008

2008 just entrenched demographic groups further into the party they were already voting for. It didn't change the way anyone voted.

Given the years picked and the board this is in, I'm assuming Turing test meant congressional elections.

Realignments:
1896
1932
1980

Mini-realignments:
1912
1948
1964
1968
1992

It's too early to tell if 2008 was a realigning election or not.

Electoral maps aren't what all realigning presidential elections are about. They're not the be-all/end-all. Realigning election of 1896 wasn't about William McKinley realigning the map. And realigning select states, over time, have been gradual.

As for what you claimed: Virginia carried Republican in all ten cycles of 1968 to 2004 (even with Democratic presidential wins from 1976, 1992, and 1996). The state flipped Democratic for Barack Obama in the realigning election of 2008 and carried for his re-election in 2012.

Also: Numerous counties carried Democratic, in 2008, for the first time since 1964, the election that had preceded a Republican presidential realigning period. They included: Virginia's Loudoun (Leesburg) and Prince William (Manassas) Counties; Ohio's Hamilton County (Cincinnati); Colorado's Arapahoe (Littleton) and Jefferson (Golden) Counties; Nevada's Washoe County (Reno); and New Mexico's Los Alamos County (Los Alamos). These were in states which were 2008 Democratic pickups; 2008 Democratic holds; and 2008 Republican holds. Noted especially, from 2004-to-2008 Republican: Texas's Dallas [Dallas] and Harris [Houston] Counties carried Democratic first time since 1964. (This also manifested in some counties which included ones in the following states: Illinois, Michigan, New Jersey, Pennsylvania, and Wisconsin. More can be accounted for; but, this is my response for now.)

I meant Congressional Realigning elections

[Orser67]

I made this chart of wave elections (>20 House seat gain) that has a lot of the major waves.

I think there have only been three true realigning elections (in which one party gained or lost a decisive advantage that lasted for decades) in the last 120 years:

1894: Democrats had generally won the House since the 1870s. After this election, Republicans generally dominated Congress, though there was a relatively brief interruption in the 1910s.
1930: After this election, Democrats generally controlled both Houses of Congress until the 1990s.
1994: Though Democrats had experienced some competition in the 40's, 50's, and 80's, they generally had the advantage in both houses of Congress until this election. Since then, the GOP has almost always had the House and both parties have been competitive in the Senate.

2010 brings in the Tea Party Congress and allows some state legislatures to entrench the hard Right in Congress (which may have even longer effects).

In 2012 many states had so gerrymandered their Congressional districts that Democrats needed a 54-46 split of the popular vote to get a majority in Congress, which is unlikely to ever happen.

We now have government of the economic elites,  by the economic elites, and for the economic elites  at the expense of everybody else for the next few decades. If that isn't a realignment, then what is?
