Congress’ prime ministerial candidate for 2019 elections is strange, to put it mildly. He has an uncanny habit of having an empty look in his eyes as he smiles awkwardly at inappropriate times. The latest addition to this long list of embarrassing smiles happened today as Congress President Rahul Gandhi paid a visit to the ailing DMK patriarch Karunanidhi, who is undergoing treatment in Chennai’s Kauvery Hospital.

We had earlier reported how Rahul Gandhi has the most inappropriate timings for showing his teeth in grim situations.

Wonder what goes on in his mind.
